Are Zippy Lipos safe with a Castle MMM Speedy?

And on a side note the packs performance is off the charts!!! Thanks Mike!

Nope....I didnt even see that one! I'll have to look that one up....should make for some good reading!

ill sum it up for you, i was showing my friend the power of brushless and mistakenly grabbed my series connector that i normally use for my 2s batts instead of my parallel one....truck ran fin for a minute or two, and surprisingly i didnt even no there was a problem until the truck just stopped....just a really stupid mistake.

Don't get me wrong, I love the Castle Creations stuff, had 3 MM's all were utterly flawless, but the MMM has me concerned.

Is it a reliable speedy, and could I recommend it to people as a reliable speedy?

At the moment, I don't think I could. I'd back the Hobbywing 150A to be more reliable particularly on a 6s config with Zippy lipos.

if you have bottom end packs you just cant expect them to perform the same as top end packs. ie. dont try and draw a ridiculous amount of power from them. Dont try and run a 10kg all alloy emaxx at 70mph. gear down!

I was running an erevo on 7s1p a123 through a MMM geared for 35mph and nothing ever got hot or broke or exploded or whatever, and A123s are notorious for shocking voltage drop. I just wouldn't attempt to gear it to 70mph and expect nothing to go wrong unless I had some top end (ie PQ or whatever) battery packs.

Some people just want to go faster than they need to. I've geared cars to go stupid fast, and its pointless. gets boring very quickly once you do it.

Wow, it seems like the same question is just getting bounced around here.

A zippy lipo is not much different from any other chinese lipo. If you can correctly estimate the wattage output of your setup you will able to accurately pick a lipo that will work.

Hpi includes the 25t pinion to be used with phatline tires to get the advertised 62mph. No other reason than that.

Getting 40mph out of a MT like the flux with 4s is not the easiest thing for a batt. Getting the same mph out of a 6s setup will pace less load on the batt. The gearing will be lower, the output of the motor will be the same (same top speed) and the voltage will be 50% more... So the amp draw will be considerably lower. So while you need a 4s lipo capable of 130-150 amps cont, you can get away with a 100-120 amp cont capable 6s lipo.

This is pretty basic stuff, if you cannot get a grasp on this you may need to go back to nitro or nikko...

i agree nicely explained! i like most people these days can't afford much wanting great performance but with a light wallet i might rethink using zippy packs and look for something else??

[truggyracer1]

what if i ran 2 5000mah 3s zippys to a MMM? would i be seeing the same kind of spiking?

I will put the performance of my packs against any other out there. The recent failure that happened to be using my packs is of a different type than described in this thread - the gearing was low enough for even the lower end packs when the failure occurred and seems to be unrelated to the batteries - I am not going to speak for Castle or anyone else on the particulars, but i can say with certainty that my batteries are NOT a problem, as I did pretty extensive testing (almost a year) before offering the packs for sale. :)

I thought that as well (regarding the type of failure), but didn't feel comfortable enough with my knowledge level to say one way or another.

So wait, you've tested ALL the batteries you sell on your site to be gaurenteed to power a Flux without killing it?

No, he is referring to the packs he makes.

Well lets not put words in my mouth here - there are far too many variables - if you used a 4s 2600mah pack in the Flux geared for 50mph, I would expect problems. The packs we sell are top quality, but the customer still has the responsibility to select the proper "tools for the job". A properly selected pack and proper gearing with any of the packs we sell will minimize the possibility of failure - specifically battery related failure. Nothing has 100% reliability, and there are many factors that can cause failure - the key is to minimize the potential causes in order to maximize the reliability - this same thought can be applied to anything you do and is the real message here.
Zippy or Flightmaxx in and of themselves are not a "cause of failure" most likely - its the combination of a lower end battery and unrealistic expectations leading to unrealistic operating conditions.
If you run a Ferrri on low grade gasoline, you have nobody to blame but yourself when it develops a ping and runs like crap. If you can't afford "premium", then get a Ford. The same message applies here - if you run lower grade batteries, you must lower your performance expectations and make the appropriate gearing and setup considerations to ensure longevity. :)

I agree to a point Mike, but for most of the people out there, highend stuff is not necessary. Case in point below.

I'll take my Zippy powered Savage (that is used for bashing) and run it against a comparable Savage that's running batteries that cost 3 times what mine cost, and my truck will run right with it. I don't have to lower any expectations with my truck...I actually had to detune it to run it!

Unless you are gearing to the moon and planning to put one hell of a load on your electrical system, as in top speed challenges or the like, I see no good reason to blow $$$$$$ on highend battery packs. The average basher will be served just fine by running the appropriately sized Zippy packs or some other economical packs. I'm a testament to that. Zippys have gotten a bad wrap and frankly, it's not warranted. Many, many people involved in all aspects of this hobby from land to water to air are running Zippys successfully, and that in and of itself speaks volumes.

curious, waht battery is the other savage running?

because i have the complete opposite results. My NEU outperform my zippy packs any day all day. and dont even get me started on my maxamps....

After reading and rereading this I'm going to be err on the side of caution.

Polyquest 6000mah 25C 3s Lipos
http://www.rc-monster.com/proddetail...pq3s6000mah25c
Would they be more appropriate?
